Phosphoric acid can be used to clean scale (calcium carbonate) from water fixtures like taps by reacting with it to form products that dissolve easily. warming the phosphoric acid solution would -

a. remove less scale.

b. remove more scale.

c. remove the scale faster.

d. remove scale less quickly.
